COIN-CONTROLLED CIRCUIT MAKING AND BREAKI NG APPARA'TUS'FOR PHONOGRAPHS.

SPECIFICATION forming part of Letters Patent No. 778,305, dated December27, 1904. Application filed April 26, 1904. Serial No. 204,935.

To all whom it may concern:

Be it known that I, ARTHUR W. COLE, a subject of the King ofGreatBritain, and a resident of West Hoboken, county of Hudson, and State ofNew Jersey, have invented certain new and useful Improvements inCoin-Controlled Circuit Making and Breaking Apparatus for Phonographs,of which the following is a specification.

The invention consists of novel means of closing the phonographoperating circuit when the coin is dropped in theslot, maintaining theclosure, and breaking it automatically when cessation of the operationof the machine is due, as hereinafter described, reference beingmade tothe accompanying drawings, in which- Figure 1 is partly an elevation andpartly a vertical section of the apparatus of my invention. Fig. 2 is aplan view. Fig. 3 is a detail in vertical section on the line 8 3 ofFig. 1 as seen looking in the direction ofv the arrow. Figs. 4: and 5are details in section on line 2 2, Fig. 2, showing some of the partsattached to thelphonographfor breaking the circuit when on the return ofthe diaphragmcarriage to the starting-point.

The apparatus herein shown is mainly the automatic circuit-closingdevices for closing the circuit and setting the phonograph in motion bythe effect of a coin dropped into the coin-receptacle. It is thereforeunnecessary to show the phonograph any further than the reversing-screwof the diaphragm-carriage and the attachment falling into gear with saidscrew when the diaphragm-carriage is released from the feed-screw forreversing the carriage.

' The diaphragm-carriage-reversing screw is represented at a, Figs. 2,4:, and 5. t repre-.

sents a knife-shaped blade carried by a staff 0, attached to thediaphragm-carriage, which by the turning of a flat blade at at theproper time is thrust up into engagement with screw 60 for reverselyshifting the diaphragm-carriage, the normal positions of said blades 6and 61? being shown in Fig. 4:, in which the screw has no effect onblade 6. The means for so turning blade at is well known in connectionwith phonographs and need not be shown or described.

The respective wiresc f of the circuit have their terminals immersed inmercury-cups g h, respectively.

' A yoke-shaped circuit closing and breaking wire c' is carried on arocking support 1', pivoted at Z2, with its terminals in such relationto the mercury-cups that in one of the positions ofthe rocking block(the same that is shown in the drawings);one terminal will lackconnection with the mercury and the cir-. cuit will be broken; but inthe reverse posi- I tion of said block both terminals will connect withthe mercury-cups and the circuit will be closed.

The rocking block is also attached to the staff Z, that carries at oneend the coin-recep- I tacle m, and is poised by a weight n near theother end, so that when no coin is in the receptacle m it will shiftupward; but the coin dropped inwill overbalance the said receptacle andelevate the other end of the staff Z, at the same time escaping from thereceptacle m.

A gravitating-hooko-swings under the end of the staff that is thuselevated and holds it up, and while so held up maintains the circuitconnection the requisite predetermined time.

When the knife 6, engaged with the reversing-screw a,-nearly reaches theend of its reverse movement, the end of said knife collides with an arm19 on a vertical rock-shaft 9, carrying a tripping-arm 1", which bearsagainst the gravitating hook 0 and trips it out of engagement with staffZ, which falls to a level positionready for reception of another coinfor another operation.

What I claim as my invention is The combination with the "phonographreversing-screw and its coacting blade, of the mercury-cups containingcircuit-terminals re-- spectively, the rocking yoke-circuit makingtripping-arm on said rock-shaft controlling and breaking Wire alsohaving its terminals the gravitating hook. 1 in said cups respectively,and mounted on the Signed at New York this 22d day of April, stafl ofthe rocking coin-receptacle, said re- 1904:.
